Experimental results with electrical stimulation of the oculomotor nucleus in cats show that central control of accommodation is complexly dependent on stimulus frequency and on location within the nucleus. A place-frequency theory of central control of accommodation is postulated to account for positive and negative accommodation and is expanded to account both for accommodative convergence and convergence accommodation.
